I was going 76mph down a hill and it died on me. I lost power. I tried electric start but it wouldn’t turn over, I bump started it and it turned over but it sounded like it was bogging out but eventually ran perfectly fine. When I got home I noticed a ticking sound. I’m looking to fix the problem but don’t know where to start. Do you guys think a top end rebuild will fix it or do u think it’s bottom end? Thanks
